Advantages

Carry out prototype development and power consumption simulation easily without purchasing development tools

  1. Easy to try out.
    You can carry out initial evaluation for developing with the RL78 Immediately and free of charge.

    • TThe virtual board simulator of the integrated development environment (e2 studio) allows you to check the operation of the RL78 on a virtual board without having to prepare an evaluation board. The virtual board simulator allows simulation of not only the CPU and peripheral functions of the microcontroller, but also external components such as switches, LED, and potentiometers. You can make observations and carry out serial communication at the microcontroller pin level.
  2. Estimate power consumption easily. Calculate consumption current before starting development.


    • You can use the consumption current calculator to easily calculate consumption current before starting development, to avoid the power consumption of the system becoming higher than expected. Simple set the usage conditions — no need to write a program — to calculate battery life and consumption current over time.
  3. Compute peak current and battery life using a high-precision consumption current simulator.


    • The consumption current simulator of the integrated development environment (e2 studio) allows you to analyze programs and compute consumption current highly precisely. It can also display a graph of consumption current over time.

Experience ultra-low power consumption using the consumption current calculator

About the consumption current calculator

Consumption current can be calculated immediately simply by setting the peripheral functions of the RL78 that are to be used.
Consumption current including peripheral function operation can be calculated, allowing evaluation to be performed without programming.

Easy-to-set peripheral functions
No need to program. Current calculations can be made simply by performing settings on a screen on the website.
Experience ultra-low power consumption
Consumption current including peripheral function operation can be calculated, so you can see ultra-low power consumption in numerical values.
Evaluate immediately
Current calculations can be made without building a prototype, allowing you to immediately evaluate if it can be adapted to your product.

Evaluate immediately using the integrated development environment

About the integrated development environment

By using the new virtual board simulator included in the web simulator, prototyping and evaluation can be carried out immediately using just the integrated development environment without purchasing a development tool for the RL78. Switch inputs, LED outputs, potentiometer inputs and other I/O can be simulated on the virtual board, and I/O pin levels can be observed, allowing for easier and faster evaluation.
Furthermore, the high-precision consumption current simulator that is also included enables the change in consumption current to be calculated for each step of the user program, making it possible to compute average and peak current, which in turn allows the smoothing of peak current to be considered and battery life to be calculated.

Start evaluation immediately:
I/O of switches, LEDs, potentiometers, and so on can be activated in the virtual board simulator of the integrated development environment, allowing user programs to be evaluated immediately.
More precise power design:
Consumption current can be calculated for each step of the user program. Knowledge of the average and peak currents facilitates the consideration of smoothing of peak current and the calculation of battery life.
Easy simulation evaluation:
Evaluation of peak current and external signal inputs, difficult to confirm in an actual device, can be conducted using the simulator.

Application Notes & Sample Code

Introduction to the RL78 Family

The RL78 has achieved the lowest level of power consumption in the industry, with a full lineup of products ranging from 10 to 128 pins and ROM sizes from 1 to 512 KB. A 32 MHz ±1% high-precision, high-speed on-chip simulator and low voltage detection circuit can be incorporated to reduce system costs.

Introduction to the RL78/G10

Low pin count, compact, low power general-purpose microcontrollers recommended for small electronic devices and sub-microcontrollers

RL78/G10 microcontrollers realize the industry's lowest level of consumption current (CPU: 46 μA/MHz, standby (STOP):560 nA). With an on-chip oscillator, A/D converter, comparator, and more, and a 10/16-pin package lineup, they support more compact system size. These low pin count microcontrollers are perfect for small consumer electronics.
